Mining the R&D innovation performance processes for high-tech firms based on rough set theory

The research and development (R&D) innovation of firms continues to be viewed as an important source of competitive advantage to academics and practitioners. To explore and extract the R&D innovation decision rules, it is important to understand how the R&D innovation rule-base works. However, many studies have not yet adequately induced and extracted the decision rule of R&D innovation and performance based on the characteristics and components of the original data rather than on post-determination models. The analysis of this study is grounded in the taxonomy of induction-related activities using a rough set theory approach or rule-based decision-making technique to infer R&D innovation decision rules and models linking R&D innovation to sales growth. The rules developed using rough set theory can be directly translated into a path-dependent flow network to infer decision paths and parameters. The flow network graph and cause-and-effect relationship of decision rules are heavily exploited in R&D innovation characteristics. In addition, an empirical case of R&D innovation performance will be illustrated to show that the rough sets model and the flow network graph are useful and efficient tools for building R&D innovation decision rules and providing predictions. We will then illustrate that integrating the flow network graph with rough set theory can fully reflect the characteristics of R&D innovation, and, through the established model, we can obtain a more reasonable result than with artificial influence.     

Destination competitiveness: evidence from Bali

Within the dynamic global tourism industry, understanding the reasons for a destination's competitiveness is essential in order to enhance its performance, facilitate more effective destination management, and inform its overall sustainable economic development. This paper applies Kim and Wicks’ (2010, July 30. Rethinking tourism cluster development models for global competitiveness, international chrie conference-refereed track, University of Massachusetts) tourism cluster development model to Bali – a small, mature destination in the developing economy of Indonesia. It demonstrates that there are complex relationships between: (i) cluster actors; (ii) barriers preventing effective networking; and (iii) the significance of these interactions for the local host community. This paper contributes to the debate by addressing new and different attributes and actors such as transnational corporations, universities, and the concept of co-opetition, as being significant attributes in Kim and Wicks’ initial model. Through a qualitative approach involving N?=?23 semi-structured interviews, this paper illustrates intricate issues and relationships that are identified in Bali, a small mature destination. Purposive sampling methods were employed to generate a range of key stakeholders who informed our understanding of ‘cluster actors’ in Kim and Wicks’ terms. The systematic examination of these key tourism elements provides a detailed analysis of the destination's strengths and weaknesses, and a more nuanced understanding of what facilitates a destination's competitive position.     

Estimating the environmental effects and recreational benefits of cultivated flower land for environmental quality improvement in Taiwan

The main purpose of this study is to measure environmental effects and recreational benefits under different hypothetical scenarios program, involving quality improvement in Tien‐Wei Highway Garden, which is the biggest cultivated flower land in Taiwan. The contingent behavior model was adopted. The data combined actual number of trips under current quality of environment combined and the intended number of trips for expected scenarios of environmental quality improvement and congestion mitigation. For the empirical model, on‐site Poisson model was performed to correct truncated and endogenous stratification issues from on‐site surveys. The results show that the estimated average consumer surplus is greater in contingent behavior method than the one in the traditional travel cost model. Also, the estimated recreational benefits in contingent behavior method are more precise than those in the traditional travel cost method. The environment benefits to consumers are communicated with the programs that changes in environment quality. Meanwhile, the incremental economic benefits comprise the gain associated with the improvement of environmental quality.     

REVISITING BOOKBUILDING VERSUS AUCTION IPOS: A PERSPECTIVE OF INFORMATIONALLY EFFICIENT PRICES IN THE AFTERMARKET

We compare price efficiency between auction and bookbuilding initial public offerings (IPOs). Our empirical results fail to support the prevailing conjecture that bookbuilding IPOs are more price efficient than auction IPOs. We find statistical insignificance between two IPO samples or weak evidence for the opposite hypothesis. We add to the evidence that auctions yield aftermarket price efficiency equal to that of bookbuilding or are statistically indifferent when measured by market microstructure and Center for Research in Security Prices (CRSP) data. We also examine whether underlying price efficiency forces reflect the relative presence of informed institutional and retail investors, aftermarket price support, and divergence of investor expectations.     

Trade Liberalisation and the Wage Skill Premium in Korean Manufacturing Plants: Do Plants’ R&D and Investment Matter?

This paper examines the effects of output and input tariff reductions on within‐plant wage skill premium in Korean manufacturing plants. We find evidence that output tariff reduction interacts differently with plants’ R&D and investment behaviours, respectively, to affect wage skill premium. More specifically, output tariff reduction increases wage skill premium mostly in R&D‐performing plants while reducing it mostly in plants making positive facility investments. While there is weak evidence that input tariff reduction increases wage skill premium, no such interactive effects are found. One story behind our results is that, although both R&D and facility investments may respond to changes in profit opportunities due to output tariff reductions, R&D raises the relative demand for the skilled workers while facility investment, an activity of increasing production capacity, raises the relative demand for the unskilled workers.     

Safety Risk Management in Construction Worksites

ABSTRACT: This study in safety risk management of construction worksites in Singapore stems primarily from recent concerns following several fatal accidents. A greater need for safety is apparent, as the reports from the Ministry of Manpower have shown that construction injuries remain disproportionately high compared to the total number of industrial accidents. The main objectives of this study are to ascertain the safety hazards faced by construction workers and the measures to deal with these hazards.
A questionnaire survey was sent to 150 randomly selected contractors in early November 1999. A 36 percent response rate was obtained. Interviews were conducted with various professionals in the insurance and construction industries to solicit information from the perspective of the practitioners, so that a better understanding of both industries could be achieved. Results indicated that the contractors agreed that practicing good risk management is important. The results of this study are useful to employers in the construction industry who are responsible for providing a safe work environment for workers, as well as to practitioners in the insurance industry involved in construction projects.     

An Analysis of Disaster Risk Management Practices in the u.s. and Singapore

ABSTRACT: This study outlines the framework of the Disaster Recovery Planning (DRP) process and describes the key steps in preparing a DRP. It also identifies the essential characteristics and core elements of the DRP and highlights the critical success factors. It provides a recommendation on the process of DRP that companies can adopt, to help them prepare a comprehensive, well-documented, and cost-effective DRP that is workable. Survey data are used to find out whether DRP is widely practiced in Singapore and the U.S. The survey questions aim to identify the various DRP arrangements an organization has when a disaster strikes and the provisions that are included in its general contingency plan, if any. The survey results for the two countries are analyzed to evaluate why the level of DRP differs so greatly between the U.S. and Singapore.     

Non‐linear finance–growth nexus

This paper revisits the question of whether the finance–growth nexus varies with the stages of economic development. Using a novel threshold regression with the instrumental variables approach proposed by Caner and Hansen (2004) to the dataset used in Levine et al. (2000) we detect overwhelming evidence in support of a positive linkage between financial development and economic growth, and this positive effect is larger in the low‐income countries than in the high‐income ones. The data also reveal that financial development tends to have stronger impacts on capital accumulation and productivity growth in the low‐income countries than in the high‐income ones. The findings are robust to alternative financial development measures and conditioning information sets.     

Rural-Urban Wage Differentials,Unemployment, and Efficiency Wages: An Open Economy Policy Analysis

This paper analyzes the desirability of various policies designed to counteract the distorting nature of an equilibrium rural-urban wage differential in a small, open, two-sector economy with urban unemployment. A dual labor market model with an efficiency wage in the urban sector and urban unemployment is analyzed for the distributional and national output effects of an urban wage subsidy, an urban production subsidy, and a tariff on the urban good. While a small subsidy or tariff raises the value of national output, redistribution effects may limit the viability of intervention. However, subsidies can also be Pareto improving policies.
